A biopsy forceps device is provided for obtaining tissue samples at a site within the body, while maintaining access to the site through an access lumen of the biopsy forceps. The device includes an elongate tubular body for introduction into the body and navigation to an area of interest. An inner tubular member having a lumen, or a plurality of lumens, extends through or adjacent the outer tubular member, from the proximal end to the distal end, where cutting jaws are provided. The cutting jaws are rotatably mounted at the distal end of the device and are controlled by movement of the inner tubular member. The inner tubular member is coupled with a handle portion allowing control of the cutting jaws at the proximal end. Access to the lumen of the inner tubular member is gained at the proximal end, where a luer fitting is provided. The lumen of the inner tubular member has a removable optical fiber disposed therethrough and allows for a variety of medical instruments to be inserted so that the instruments can be used coaxially in the same location as where the biopsy sample is taken.
